IMPROVEMENT IN PRESSES.

Specification forming part of Letters Patent No. 30,500, dated October23, 1860.

To aZZ whom it may concern.-

Be it known that I, ADoNrJAH RANDEL, of the city, county, and State ofNew York, have invented a new and Improved Press for lCom` pressingSubstances for Baling and other Purposes; and I do hereby declare thatthe following is a full, clear, and exact description of the same,reference being had to the annexed drawings, making a part of thisspecication, in which- Figure l is a vertical section of my invention,taken in the line .fc fr, Fig. 2; Fig. 2, a vertical section of thesame, taken in the line 3/ y, Fig. 1.

Similar letters of reference indicate corresponding parts the twofigures.

The object of this invention is to obtain a press of simple andeconomical construction, which will admit, under the same application ofpower, of giving two different degrees of pressure, so thatth'esubstance may be compressed expeditiously and in a proper manner, andexcess of powerbeing dispensed with for speed, and the latter dispensedwith when power is required. V

'Io enable those skilled in the art to fully understand and construct myinvention, Iwill proceed to describe it.

A represents an upright framing, the principal part of which is inclosedto formapressbox, B, in which the substance to be compressed is placed.The box B is provided with a door, C, at each end.

D is a follower or plunger, whichisplaced within the box B and allowedto rise and fall freely therein. This follower or plunger has twovertical rack-bars, E E, attached to it, said bars being each providedwith three racks, a a b, the racks Z) being at the inner sides of thebars, and the racks a a at the two adjoining sides. (See Fig. 2.) Therackbars E E pass through a cross-head, F, the ends of which are fittedin slots at the upper parts of the framing A, and into the racks b ofthe bars E pinions c gear, said pinions being on shafts cZ (Z, which areconnected at one end by gear-wheels e e. One of the shafts d has aspur-wheel, G, on it, and this wheel has a pinion, f, gearing into it,said pinion being on a driving-shaft, y, which has a crank, 7L, at oneend of it. Each bar E has a frictionroller, i, bearing against its outerside. The racks a a of the bars E have pawls, j, which catch into them,and to cach end of the follower or plunger D there is attached a pawl,k, and these pawls are in contact or engage with racks Z Z at the innersides of the framing A, as shown clearly in Fig. l.

From the above description it will be seen that by turning the shaft g,the follower or plunger D may be raised or lowered within the box B, andwhen the follower or plunger is forced down and the substance below itcompressed the racks a Z and pawl j prevent the follower or plunger fromcasually rising.

rEhe above arrangement of gearing admits of a speedy movement of thefollower or plunger D, and it is used only at the first move ment of thefollower or plunger. 'Vhen more power is required, the follower orplunger is operated through the medium of the crosshead F, the pawlsjjbeing tted in the racks a. This crosshead has an arm or bar, G',attached to each end of it. These arms or bars extend down at each sideof the framing, and they are fitted at their lower ends on eccentrics mm, which are placed on the ends of a shaft, H, which passes through thebase I of the framing A. At the ends of the shaft I-I there are securedspur-wheels J J. These wheels gear into pinions a a,which are placed onshafts o o, the outer ends of which have wheels p p on them, whichwheels gear into pinions q q on shafts r r, to which the power isapplied. Then the follower or plunger D has been forced downsufficiently far by the gearing connected to the cross-head F, andpreviously described, the shafts r r are rotated, and the shaft H isrotated through the medium of the gearing J J a n p p qq, and theeccentrics m m will draw down the cross-head F, and the follower orplunger D will be forced down with an increased power. In this latteroperation the pawls 7c k and racks Z Z prevent the casual rising of thefollower or plunger when the power is removed from the shafts r 9', thepawlsj and racks ,a forming the connection between the cross-head F andraclcbars E E.

The relative size of the gearing J n p q may s small7 compared With therst movement of F, provided With the pawls j, and actuated the followeror plunger. through the medium of the eoeentrics mm, all

Ido not claim separately any of the Wthiubeugarrauged essentially as andfor the purdesoribed parts; but pose Set forth.

I do claim as new and desire to secure by Letters Patent- I Therack-bars E E, provided with the racks a l Vtnesses: a b, and actuatedthrough the medium of the L. W. BENDR, pinionsoc, in conneetionwith thecross-head JAMES LAIRD.
